• Access 2007 can I capture the "clicked" field using an OnClick event on a report?

  - by Aaron Quince

  In Access 2007 I want to be able to click on a name field in a report and call a separate report with personal information about the person who's name was clicked to start the event. This would be as an alternative to creating a subreport or including the subreport fields in the main report in the interest of saving space. How do I reference the value of the clicked field for use in a query called with the OnClick event? Thanks for your help.

• How to store a scaleable sized extensible event log?

  - by firoso

  Hello everyone! I've been contemplating writing a simple "event log" that takes a paramater list and stores event messages in a log file, trouble is, I forsee this file growing to be rather large (assume 1M entries or more) the question is, how can I implement this system without pulling teeth, I know that SQL would be a possible way to go. XML would be ideal but not really practical for scaleability if i'm not going nuts. Example Log Entry -----Time Date-------- ---------Sender----------------------- ---------Tags---------- --Message---------- 12/24/2008 24:00:00 $DOMAIN\SYSTEM\Application$ :Trivial: :Notification: It's Christmas in 1s

• Resize event does not fire in Firefox, but I need to handle focus when FancyBox is shown

  - by Christian Nielsen

  I am working on a solution where I need to have the first input field selected when a fancybox is shown. I have tried reacting to the resize event, which works fine in IE but not in Firefox. Also tried reacting to the click event on the link that opens the box - but aparently this is too early so some other element steals focus afterwards. Any ideas??

• How to adjust asp.net URL routing based on domain/host?

  - by DrewF

  What's the best way to adjust the path destination for a routing table created in the global.asax Application_Start event based on the domain/sub domain/host? The following worked in IIS6, but with IIS7 the request object is decoupled from the Application_Start event and therefore does not work anymore: Dim strHost As String = Context.Request.Url.Host Dim strDir As String = "" If strHost.Contains("domain1.com") Then strDir = "area1/" Else strDir = "area2/" End If routes.MapPageRoute("Search", "Search", "~/" & strDir & "search.aspx")

• C# Is it possible to wire up an event to a method when it is finished?

  - by Martijn

  I have a .dll file and in there, there's a method called A. When I call that method I'd like to call a method of my own, method B. So my question is, is it possible to call method B immediately when method A is finished? Offcourse I can call method A and after that call method B manually. But I was wondering is there a manner to do this automatically, maybe with an event? So when method A is finished the event gets fired somehow and method A is called.

• Javawebparts Ajaxparts: Using same Axis event multiple times in signle form.

  - by Bloodboiler

  I'm using Javawebparts Ajaxparts and would like to use one axis event multiple times in a form. Problem is that std:InnerHTML responseHandler takes its target html tag id in axis-config.xml so it seems impossible to reuse the definition when only thing that should change is the target tag id. Is there a way to set responseHandler parameters on the the page where it is used (in asix:event tag or someting)?
